I just felt like in the late game runners would be just standing in the pile and constantly spamming YEET, almost never gathering up a beautiful pile and walked it back to the base. I think both ways look cool though. And with this nerf, in the late game, you are constantly still seeing YEETs triggering, just not as often from the same dwarf.
Increasing it per carried ore would work kinda similarly in the end, you'd still have similar set odds of YEETing before the pile is full and runner returns, but less chance with bigger piles makes a bit more flavorful sense I suppose.
I am not yet entirely sure of this change and it will become clearer as the game develops, but if I do keep the CD, I was thinking of adding a T4 prestige upgrade that removes CD. Then the next rank of this upgrade would also make runners start the game with gorilla arms T1 already bought, as a real late game powerful/fun prestige upgrade (and btw at this point I'm also thinking of making prestige tier equal PP cost)
